There was an error in printing (they were upside down) and I contacted support. They got back to me fast and are replacing the mask. Despite the error in production the masks are very nice! They are cotton, double ply with a pocket for a filter - which is the best you can do. I enjoy the cartoons on them as well (LOVE the amoeba sisters!)

I got the water molecule mask. It's cute, a little short top to bottom as the other review mentions but I think it would work okay for short term. I have a feeling it would end up sitting ON my mouth after long wear. It is two layers but thin, t-shirt material, not tight woven cotton as the CDC recommends. There is space to insert a filter but it would have to be a small one. But worst of all, the nose wire is way off to the side! I wear glasses. This mask is useless :( I have spent the past 20 minutes trying to move the nose wire to no avail. Pretty disappointed with this product, especially at $10. The nose wire is located between my fingers in the picture.

First off, I love the Amoeba Sisters and this print is adorable. One of my students said "you have organelles on your mask!", so it was great to have it recognized! I also really appreciate that it has the filter pocket. However... 1. There is no nose clip, so it leaves a wide open space beneath the eyes. 2. It is a wee small, so the gap on either side of your nose is substantial and difficult to adjust if you have a wide face. It also puts pressure on the bridge of my nose, which causes discomfort over time. 3. It is also small in regards to reaching from my chin to my nose, so there is limited coverage. It fogs up my classes and requires frequent adjustment. Mask fit is so essential to effective protection, so that is a major issue for me, hence the 3 stars. If you have a thin/small face, or if you are ordering this for a child, it could be perfect for you!
